hey kingfish, I know I'm 2 years late to this post but I happened to have the same issue, and now that this is a private thread I can no longer see it, do you still have a solution that's not private?
With laptop APU's you update the APU...one driver. This updates the onboard and discrete graphics. There will be no more updates for this "Legacy" graphics.
Important Note for Laptop and All-In-One (AIO) PCs
AMD recommends OEM-provided drivers which are customized and validated for their system-specific features and optimizations.
